Building decks

In progress Free Last reviewed: 24 Oct 2026

A deck consists of cards from your collection; deck size and copy limits set the rules.

What is it for?

Beta phase note: The card game is not set up in the beta. The feature is built, but not available to you at the moment.

In the “Decks” tab, under “My decks”, you see each deck with “{count} / {max} cards” and “Power weight {weight}”. You create a deck with “New deck”. Without decks, it says “You haven't created a deck yet.” In the deck editor, “Deck contents” is on the left and “My collection” on the right, with the field “Search card…”. You add cards with “Add” and remove them with “Remove”.

A deck only contains cards you own, and at most as many as the deck size allows (default: 25). How often a card may appear depends on its rarity, for example four Common or one Legendary. The collection shows how many copies of a card are still “available”. A deck with fewer cards than the deck size can be saved, but not used for a duel.

The power weight comes from the card weights and is used to find opponents, so decks of very different strength do not meet. With “Edit” you change a deck, with “Delete” you remove it after a confirmation prompt.

How it works

  1. In the “Decks” tab, choose “New deck” and enter a “Deck name”.

    What you see afterwards: The deck editor opens.

  2. Under “My collection”, search with “Search card…” and choose “Add” on a card.

    What you see afterwards: The card appears under “Deck contents” and the count goes up.

  3. Choose “Save”.

    What you see afterwards: The deck appears in the list with its card count and power weight.

  4. Choose “Back to deck overview”.

    What you see afterwards: You see your decks.

Who can do this?

All signed-in accounts build their own decks and only see their own.

Your data

Illumentis stores the deck name, cards and power weight. When a duel starts, Illumentis records the state of your deck for that duel; later changes only affect new duels.

Limits

The deck name can have at most 60 characters. The operator sets deck size and copy limits; the default is 25 cards and one to four copies depending on rarity. If card values or limits change, a saved deck can become invalid and has to be adjusted before the next duel.

Frequently asked questions

How many cards does a deck have?

By default 25. The operator sets the value; the interface shows it as “{count} / {max} cards”.

How many times may a card appear in a deck?

That depends on the rarity. Default: Common four, Uncommon three, Epic two, Legendary and Mystic one.

Can I play with an incomplete deck?

No. To find an opponent, the deck needs exactly the deck size.

What is the power weight?

The sum of the weights of the cards in the deck. It steers the opponent search.
